Mars' Whirling Dust Devil

As on the Earth, many processes can move material down a Martian slope. This graphic compares seven different types of features observed on Mars that appear to result from material flowing or slidi...

This map shows the route driven by NASA's Curiosity Mars rover from the "Bradbury Landing" location where it landed in August 2012 (the start of the line in upper right) to a major waypoint called ...

This graphic illustrates where Mars mineral-mapping from orbit has detected minerals that can indicate where a volcano erupted beneath an ice sheet. The site is far from any ice sheet on modern Mar...

This animation shows NASA's Mars Reconnaissance Orbiter flying over NASA's Curiosity (shown in pink) as the rover lands on the Red Planet. The video is slowed down as the orbiter approaches the lan...

This close-up image of a dust storm on Mars was acquired by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter on Nov. 7, 2007.

Countdown Nears: Final Tests

The High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter acquired this image of the Opportunity rover on the southwest rim of "Santa Maria" crater on New...

This is an image of a central pit of an impact crater in the Martian ancient highlands.

This animation depicts a flyover of a meteoroid impact crater on Mars that’s surrounded by boulder-size chunks of ice. The animation was created using data from the High-Resolution Imaging Science ...

The Cerberus Fossae are a group of troughs in the Cerberus region of Mars that run roughly parallel to one another. They formed due to extension of the crust in the region. Some of the troughs, suc...

Impact Crater in Tempe Terra

This image from orbit covers an area about 460 meters (about 1,500 feet) across, in which carbonate minerals have been identified from spectrometer observations. Fractures and possible layers are v...

This artist's concept shows NASA's Mars Reconnaissance Orbiter mission over the red planet.

Recent small craters discovered by the High Resolution Imaging Science Experiment camera on NASA's Mars Reconnaissance Orbiter expose buried ice in the middle latitudes of Mars.

This global map of Mars was acquired on Aug. 2, 2012, by the Mars Color Imager instrument on NASA's Mars Reconnaissance Orbiter.

Back-and-forth blinking of this two-image animation shows movement of a sand dune on Mars. The images are part of a study published by Nature on May 9, 2012, reporting movement of Martian sand dune...

This scene shows dark sand dunes marching over the ridges created by an alluvial (water-deposited) fan in an impact crater.

This image covers a region of Mars near Nili Fossae that contains some of the best exposures of ancient bedrock on Mars.

This artist's concept of NASA's Mars Reconnaissance Orbiter at Mars features one of its instruments -- the Mars Climate Sounder -- in action.

The Mars Reconnaissance Orbiter’s Context Camera, which captured the 110,000 images that make up the interactive global mosaic, is especially useful for spotting impact craters like those seen here.

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in December 2015, at examples of the Bagnold Dunes.

This map shows the route driven by NASA's Curiosity Mars rover from the location where it landed in August 2012 to its location in December 2016, which is in the upper half of a geological unit cal...

In this HiRISE image taken within Capri Chasma, TES also detected the same crystalline gray hematite like that found at Meridiani Planum.

These dark streaks, also known as “slope streaks,” resulted from dust avalanches in an area of Mars called Acheron Fossae. The HiRISE camera aboard NASA’s Mars Reconnaissance Orbiter captured them ...

This May 2015 image from the HiRISE camera on NASA's Mars Reconnaissance Orbiter shows a location on Mars associated with the best-selling novel and Hollywood movie, "The Martian." It is in a regio...
